Description

The 74FCT16240ET 16-bit buffer/line drivers are built using advanced dual metal CMOS technology. These high-speed, low-power devices offer bus/backplane interface capability with improved packing density. The flow-through organization of signal pins simplifies layout. The three-state controls of the 74FCT16240ET are designed to operate these devices in a Quad-Nibble, Dual-Byte or single 16-bit word mode. All inputs are designed with hysteresis for improved
noise margin.

The 74FCT16240ET are ideally suited for driving high capacitance loads and low-impedance backplanes. The output buffers are designed with power off disable capability to allow "live insertion" of boards when used as backplane drivers.

The 74FCT16240ET have balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall times  reducing the need for external series terminating resistors.  The FCT162240T/AT/CT/ET are plug-in replacements for FCT16240T/AT/CT/ET and 54/74ABT16240 for on-board interface applications.
